Abstract
An audio player is connected to an automatic playing musical instrument, and command files and audio data files are prepared in the file format defined in the Red Book in the audio player, although the time data are stored in the time data fields of the longitudinal time codes, the user's data fields are available for commands to the automatic player and identification of a music data file; when a user instructs the audio player to control the automatic player for a solo performance, a quasi audio signal is produced from the command data for the solo performance; when a user instructs to a performance in collaboration with the automatic player, the audio signal, which expresses the pieces of audio data and a music data file, is supplied to the automatic player so as to reproduce the music tune through the acoustic tones and electric tones.
